There is a third green teleporter on (15,1), the starting square for one of the steel balls.

*[user:slamo]:
Here's a route for level 51, tons of possibilities here...

*[user:svimmer]:
Looks like you may not be able to phase the right wall of the basin the ball you start next to falls into... not in one %%%go at least. So delay-phasing or going round?
I guess you're using the teleporters to the fullest... i.e. if you can almost pick up an item through a tele using it %%%regularly, then if you use it at the last possible moment, you might be able to do it. Otherwise, let's see if there's a%%% ball cycle thing preventing you from taking the fastest route (looking at (-6,-5)) maybe you can do something useful %%%during that time.
*[user:slamo]:
[module:youtube|v=oP0JVVCHiI4|flashblock]
The most problematic gem is the isolated one across from the bottom left green teleporter. The marble on the rightmost %%%conveyer that Svimmer mentions does have a nasty cycle, so I grab this isolated gem instead of waiting for the marble. %%%This move pays off later as I no longer have to detour there after the area with the red gates, and I just teleport (and %%%grab a gem, why not) closer to the exit. Delay-phasing is used to get to the exit, although I only had to use one extra%%% cycle because the marble is so bogged down by the conveyer.

__Thread Discussion__
*[user:slamo]:
Tornado has been kind of disappointing. I'm pretty happy with everything before the last marble section, but that's all %%%pointless because you get severely bottlenecked and have to wait a lot in the end anyway. Oh well, I hope the playaround%%% in there demonstrates why this level is frustrating. Time to move on.
[module:youtube|v=9Ehh_gF0Uvo|flashblock]
*[user:flashthe]:
so it is not possible to follow the marble into the green portal at the bottom and come out on top?
*[user:slamo]:
There's no way to the green teleporter, at least without an invincibility powerup.

[module:youtube|v=CbHt3th7Y_8|flashblock]
I tried a few routes for this one. One route just snaked straight lines through the gems at the top and came out on the %%%bottom right, which ran into enemy issues. The other one got the rightmost ones on the floor first, and then zig-zagged %%%through the top blocks, finishing in the middle, then falling and collecting the remaining floor gems. The route in the %%%video is nice because it has a lot of flexibility in evading the missiles and ended up being the fastest.
*[user:Svimmer]:
I guess the shield wasn't making the 53 route any better? Was there a way to plan the level with the shield since you %%%knew it was about to spawn?
*[user:slamo]:
I tried grabbing it on the way to the upper right corner but it was too slow. The missiles weren't a huge issue here so%%% I don't think it would be worth it to grab it earlier.

[https://files.tasvideos.org/gameresources/dos/jetpack/level_54.png][https://files.tasvideos.org/gameresources/dos/jetpack/level_view_54.png]
There is a full fuel tank on the most bottom-right square behind a marble.

[module:youtube|v=unBoUfJHAeg|flashblock]
The route seems pretty logical, as you need fuel to finish the level...it's actually possible to go through the bulge %%%without fuel, but insanely difficult (and most importantly, slow). As usual I try to be productive while waiting for %%%missiles.
*[user:Svimmer]:
You did try alt-stepping down the "staircase" at the beginning?
*[user:slamo]:
There are two problems with alt-stepping down that staircase. First is that you don't hit terminal velocity immediately %%%after stepping off, so falling is much slower. Second is that you gain too much horizontal speed and this results in you %%%jumping over most of the gems.
*[user:Svimmer]:
Did you try phasing (-10, 3) from the left side and collecting the gem above after that? Otherwise was it possible to do%%% a frame of delay-phasing on that block?
*[user:slamo]:
You're actually right about this and I did try this before I uploaded the video. You can delay-phase that brick by %%%starting ASAP from the left side and then settling on top to collect the gem, and it is faster. The problem is that you %%%run into the same bottlenecks as before - you just barely can't get past the missile to escape from the top of the %%%bulge, and the spring under the half-tank blocks you from going down the staircase after collecting the rightmost gem. %%%In the end it makes no difference.

I feel like there are only two sensible routes here, one with the red gate and one without it. The route with the gate %%%off is 10 frames faster, probably due to the fact that it only requires one teleport instead of two and the switch isn't%%% too far out of the way.

The only major route difference I made so far is using the teleporter to get the two gems in the bottom left corner %%%early instead of picking them up when I'm nearby. It was one frame slower.
I've considered TONS of optimizations here...i.e. figuring out ideal configurations for picking up groups of nearby %%%gems, burning crates early to position myself better for the next gem, efficient pathing, etc.
I am definitely not done playing around with this level. Doing this first route has given me another idea, and maybe %%%posting this will give people other ideas. Generally it's better to start by going down, because navigating up without %%%fuel is time-consuming and the fuel is near the bottom anyway.
*[user:slamo]:
[module:youtube|v=nB4vobh6iOM|flashblock]
This is 39 frames better than the first WIP, so a bit over half a second. I actually never thought that going up at %%%first would be faster, but this route proves me wrong. I have one more idea I want to explore before I'm done with this%%% level.
*[user:Svimmer]:
So for the record you're facing subpixel problems with no obvious solution (like phasing down before the jump) with the %%% one jump where you phase a crate but aren't able to enter the space that was left? Did you try phasing the crate to the %%%left (10, 3) instead of above (10, 2)? That would save you a jump, but you'd have to jump again to collect (10, 1).
*[user:slamo]:
Yeah, for horizontal subpixels I can just phase up/down but for vertical there is no good solution (jumping up to that %%%crate at different positions results in slightly different subpixels, but none worked out). Interesting idea...it would %%%be one less jump, so it would definitely save time.
This is kind of moot now though, as an entirely different route has shaved 27 frames off WIP 2.
[module:youtube|v=y10sLLDg3g8|flashblock]
*[user:Svimmer]:
Hmm... It looks pretty logical, all the second half looks logical with the ones that are left. Unless picking up the two %%%gems at (14, 8) and (15,9) from the top after the tele instead of bottom before the tele and going right from there is %%%any good?
*[user:slamo]:
I considered this, but we're talking about phasing 5 crates to get them from the top instead of just 2 from the bottom %%%(roughly 10 frames per crate, factoring in phasing time and travel...although falling is faster, it's not THAT much %%%faster). The 2 routes for getting the cluster in the upper right are roughly the same time.

__Thread Discussion__
*[user:slamo]:
[module:youtube|v=SiaWaVE9M9I|flashblock]
Obviously the barriers are a huge problem here. The bottom is kind of OK because at least you can phase around them, but %%%the top section just traps you and forces you to wait. The period for the cycles is kind of short...overall the time for %%%this is dictated by how many cycles it takes. The second best time I got was a whole red cycle slower (about 2.5 %%%seconds). I really don't think this can be improved, as the route on the bottom is really efficient and no other route I %%%tried even came close.
*[user:Svimmer]:
I guess you tried to phase the block you start on then going left instead to collect those ones, then going through?
*[user:slamo]
That's another good route - but I would end up hitting the same cycle, so the final time would be the same as well.
